if you have no plain in playing on live or the console is already banned you can just patch your games to wave 2 and they will work with no need to reflash. you can google 360wave patcher. you will need to get the latest updates to play patched games. this is easy you can just go rent an original copy of left 4 dead 2 and take the update when you first go to play the game or you came go to m$ website and and download the update and put it on a flash drive or burn it to a disk. sounds like you have 1.5 installed. 1.5 plays wave 2 games. the newest is 1.61 it will play all new waves with is wave 5. i suggest 1.6 non-stealth as it is the last firmware yo will ever need for a non live box. you can check over at xbox scene if you want to pay somebody to reflash but i would just patch.
